I noticed the other day that I mistyped a domain name and got a Verisign page. I thought it was odd, but hadn't suspected what had actually happened. From Slashdot:
As of a little while ago (it is around 7:45 PM US Eastern on Mon 15 Sep 2003 as I write this), VeriSign added a wildcard A record to the .COM and .NET TLD DNS zones. The IP address returned is 18.104.22.168, which reverses to sitefinder.verisign.com. What that means in plain English is that most mis-typed domain names that would formerly have resulted in a helpful error message now results in a VeriSign advertising opportunity. For example, if my domain name was 'somecompany.com,' and somebody typed 'soemcompany.com' by mistake, they would get VeriSign's advertising.
